Abstract:

A theoretical model for the spatial distribution of fission fragment damage in bulk crystals of copper and germanium was developed. Calculations of the energy distribution of primary knock-on atoms and of the range and energy loss of such atoms in the lattice are combined to determine the radial Frenkel defect concentration in a cylindrical fission spike. The radial strain field associated with such a defect concentration is also calculated and applied to the theory of diffraction contrast of fission tracks in the electron microscope. Several experimental studies of fission damage in bulk materials are discussed in the light of the proposed model. Author
